A resource to allow students to practice reading typical unstructured amount of substance questions to pick out starting points (i.e. “what can we calculate first from the information given”). Students should be familiar with mole calculations first (in terms of mass = mol x Mr and mol = conc x vol), and gas calculations (including the ‘rule’ of 24dm3 and the ideal gas equation). The questions can be used as a challenge set if you ask students to carry out the calculations to their conclusion, and full workings are provided in the answer document for this. Created pretty much from scratch, so ideal for extra practice questions once you’ve exhausted other sources. Created for Edexcel A-level chemistry. Will be applicable to other exam boards.

A set of worksheets to support A-level chemistry students who may have some weaknesses in maths, or benefit from more practice in fundamental mathematical skills to improve their confidence. Most have some explanatory text on them, as they are designed for learners to access independently. Answer sheets are included, with workings shown. Worksheets included are: 01 - Rounding and decimal places 02 - Standard form 03 - Significant figures 04 - Units (converting between units) 05 - Rearranging equations 06 - Units from equations 07 - Percentages 08 - Means 09 - Ratios About me - I am an experienced teacher of A-level chemistry, having taught AQA for 7 years and Edexcel for 2 years. I have a particular interest in helping students develop their mathematical skills, and have gained an understanding of where they typically struggle in the transition from GCSE.

I have a particular interest in helping students develop their mathematical skills, and have gained an understanding of where they typically struggle in the transition from GCSE.

Designed specifically for the Edexcel A-level chemistry specification (9CH0), covering topic 2: Bonding and structure. Many of these will be useful for other exam boards too.

Sheets included: 01 - Ionic bonding 02 - Ionic bonding diagrams (dot and cross) 03 - Properties of ionic compounds 04 - Metallic bonding (including properties) 05 - Covalent bonding (including orbital overlaps and expanding the octet) 06a - Covalent bonding diagrams 1 06b - Covalent bonding diagrams 2 07 - Mixed dot and cross diagrams 08 - Covalent substance properties (simple molecular & giant) 09 - The bonding continuum 10 - Shapes of molecules 1 11 - Shapes of molecules 2 12 - Intermolecular forces (Edexcel-specific language, i.e. London forces not VdW) 13 - Hydrogen bonding (including ice and hydrogen compounds) 14 - Dissolving compounds 15 - Reviewing periodicity (a recap from Topic 1 on melting/boiling points, applying Bonding & Structure) About me - I am an experienced teacher of A-level chemistry, having taught AQA for 7 years and Edexcel for 2 years - and have been slightly frustrated at the lack of Edexcel-specific resources in that time.

Designed specifically for the Edexcel A-level chemistry specification (9CH0), covering topic 1: Atomic structure and periodicity. Many of these will be useful for other exam boards too. A full set of worksheets for the topic, built from scratch to provide an extra source of practice for students. Answer sheets included. Full workings given for mathematical questions (in this case, isotopes etc). Sheets included: 01 - Proton, neutron and electron numbers (including for ions) 02 - Isotope calculations from abundances (simple calculations to find relative atomic mass from given abundances) 03 - More complex isotope calculations (for example, where at least one isotope mass is unknown) 04 - Isotope calculations from mass spectra (using graphical data to find r.a.m.) 05 - Mixed isotope calculations (a mixture of all above types, since mixed practice improves learners’ adaptability) 06 - Mass spectra of small molecules (eg. chlorine and bromine and peak heights/ratios, but with more examples for practice) 07 - The mass spectrometer (layout and function) 08 - Electronic structure (electron configurations) 09 - Successive ionisation energies (predicting groups etc) 10 - 1st ionisation energies (across periods but also down groups) 11 - Periodicity (mainly melting points across periods 2 and 3) About me - I am an experienced teacher of A-level chemistry, having taught AQA for 7 years and Edexcel for 2 years - and have been slightly frustrated at the lack of Edexcel-specific resources in that time. I have a particular interest in helping students develop their mathematical skills, and have gained an understanding of where they typically struggle.
